pouchdb

Does anyone know how to create aggregate functions, for example avg, sum, max and min on PouchDB database. I created a simple application to test the PouchDB. I'm still not figured out how to run these commands. Thanks in advance. For example. How do you get the highest, lowest or average for the "number" field? My main Ionic 2 component import {Component} from '@angular/core'; import {Platform, ionicBootstrap} from 'ionic-angular'; import {StatusBar} from 'ionic-native'; import {HomePage} from './pages/home/home'; declare var require: any; var pouch = require('pouchdb'); var pouchFind =

We are seriously exploring Ionic, PouchDb and CouchDb as a solution to one of our requirement where we need to build a mobile app which can provide offline sync functionality and also to be platform agnostic. One of the other major requirement we have, that the data in offline mode would be persistence in nature and can grew more than 500 MB and since PouchDb is going to use IndexedDB / WebSQL adapters etc. to store data in offline mode, it has certain size limitation in mobile and web platform and also the data is not persistence in nature. Then I came across this article in pouchdb site

I am live syncing a freshly minted pouchdb (3.3.1) to an established (iris) couchdb. The initial replication happens successfully ( pause event fired). If I do info() on the Local, I get an update_seq of 362 . If I do info() on the remote, it shows an update_seq of 4201 . I think this makes sense to me: the local db has no revisions - only the leaves (i.e. there are 362 leaves in the db) whereas the remote db sequence counter reflects all the historical changes that have been made since it was first created. My question is: how can I programatically determine what the initial 'offset' in

Was there recently a change in Android Chrome's quota management for IndexedDB? I'm using PouchDB with adapter IndexedDB in an Ionic 3 Cordova app. It went pretty smooth for the last 6 months. But within the last 5 days, I received a significant increase in complaints about data not loading correctly in the app. My app requires only 3-4 MB of data. Here's what I know so far: Problem only occurs in situations with low disk space on the internal storage (even if the app is installed on an SD card) Affected devices almost always have only 16GB of internal disk space and seem to be constantly full

I have a PouchDB app that manages users. Users have a local PouchDB instance that replicates with a single CouchDB database. Pretty simple. This is where things get a bit complicated. I am introducing the concept of "groups" to my design. Groups will be different CouchDB databases but locally, they should be a part of the user database. I was reading a bit about "fancy replication" in the pouchDB site and this seems to be the solution I am after. Now, my question is, how do I do it? More specifically, How do I replicate from multiple remote databases into a single local one? Some code examples

i am new with nosql concept, so when i start to learn PouchDB , i found this conversion chart. My confusion is, how PouchDB handle if lets say i have multiple table, does it mean that i need to create multiple databases? Because from my understanding in pouchdb a database can store a lot of documents, but a document mean a row in sql or am i misunderstood? ... does it mean that i need to create multiple databases? No. ... a document mean a row in sql or am i misunderstood? That's right. The SQL table defines column header (name and type) - that are the JSON property names of the doc. So, all
